New Campylobacter-Detecting Medium Licensed

Article excerpt

A quicker, simpler way to distinguish between Campylobacter species has now been licensed for manufacture by two U.S. companies. The new culture medium, called Campy-Cefex, is specifically designed to detect and differentiate C. jejuni and C. coli mixtures of food-contaminating microbes. These two bacteria are important causes of foodborne illness.

Agricultural Research Service (ARS) is the USDA's chief scientific research agency. In 1987, ARS microbiologist Norman Stern, with the Poultry Microbiological Safety Research Unit (PMSRU) in Athens, Georgia, began developing the new medium when he traveled to Pulawy, Poland, to work with researchers Boleslaw Wojton and Kris Kwiatek at the Veterinary Research Institute. They worked together to characterize Campylobacter contamination in poultry. Previous media for detection of Campylobacter relied upon the use of new antibiotics that were unavailable in Poland. In developing the medium, Stern used the only two antibiotics he had brought with him--cycloheximide and cefoperazone.

Surprisingly, the two compounds provided superior efficacy, not only for growing Campylobacter in a culture, but also for repressing the growth of almost all other microorganisms. …
